Superimposition of structures of amylomaltase.

The structure of Thermus aquaticus amylomaltase in native form (white) was superimposed on that in acarbose-complex form (blue). Upper panels show the overall structures and lower panels indicate the enlarged view of proposed accepter binding site. This superimposition revealed a conformational change around the acceptor binding site which is caused by the binding of substrate to the second substrate binding site 14Å away from catalytic residues.
